Comparative Study on Postoperative Immobilization in Reverse Total Shoulder Arthroplasty: 4 Weeks vs. 6 Weeks of Immobilization Yields Similar Clinical and Functional Outcomes.

Background/Objectives: To investigate clinical and functional outcomes of patients undergoing reverse total shoulder arthroplasty (RTSA) using a rehabilitation protocol of either 4 or 6 weeks of immobilization. Methods: This comparative study analyzed a consecutive patient cohort that underwent RTSA in a single institute from January 2021-February 2023. Patients were assigned to groups according to the duration of postoperative immobilization and were followed up for a minimum of one year. Patient demographics, range of motion (ROM), functional outcomes using the Simple Shoulder Test (SST) and the American Shoulder and Elbow Score (ASES) as well as postoperative complications were recorded. The minimum clinically important difference (MCID) was used to assess whether the differences between the groups in SST, ASES, SWB, and VAS were clinically relevant. Results: Sixty patients met the inclusion criteria (35 patients in the 6-week immobilization group (6 WG) and 25 patients in the 4-week immobilization group (4 WG)) and were available for the total follow-up period. Similar baseline demographics were observed between the groups. Active ROM significantly improved for both groups, with abduction and forward flexion improving the most. In terms of functional outcomes, significant improvement (p < 0.001) was demonstrated for both groups (ASES, SST, VAS, and SWB). However, patients in the 4 WG reached significantly better results in VAS and SWB at 6 weeks and 3 months, as well as in ASES 3 months postoperatively, whereas both groups leveled off at the end of the follow-up period after 1 year. Taking into account the MCID, these differences for ASES at 3 months, as well as VAS and SWB at 6 weeks and 3 months postoperatively, were significant. Surprisingly, there were no differences between the groups over the entire follow-up period in terms of the SST. Conclusions: The author's findings suggest faster clinical recovery at 6 weeks and 3 months in patients undergoing postoperative immobilization of 4 weeks compared to 6 weeks following RTSA. However, clinical and functional outcomes were equal for 4 WG and 6 WG at one year follow up.

Impact of insurance payer type (medicare vs. private) on the patient reported outcomes after shoulder arthroplasty

BackgroundThis study’s purpose is to determine if there is a difference in patient reported outcome measures (PROMs) following shoulder arthroplasty (SA) based upon payer insurance type with a secondary outcome of determining if any appreciable difference surpasses the minimal clinically important difference (MCID). MethodsSubjects undergoing anatomic and reverse total shoulder arthroplasty (aTSA and rTSA) were prospectively enrolled between March 2019 – March 2021. Subjects completed PROMIS Upper Extremity (P-UE), the American Shoulder and Elbow Score (ASES), and the Simple Shoulder Test (SST) preoperatively and at 2-weeks, 6-weeks, 3-months, 6-months, and 12-months postoperatively. Descriptive statistics of baseline patient characteristics and preoperative PROMs (ASES, SST, P-UE) were compared between insurance types. Results143 patients were identified who met the inclusion criteria for this study. There were 98 patients within the Medicare cohort and 45 patients with private insurance. Patients in the Medicare cohort were older (mean age 70.5 vs 61.3 years), with high proportion of smokers, diabetics, and rTSA compared to the private payor cohort. There were no significant differences between the two cohorts with respect to outcomes scores except for significantly better SST in the private insurance cohort (69.3 versus 79.4, p=0.02). No significant differences were noted for the achievement of MCID between cohorts [P-UE (p=1.0), ASES (p=0.25), SST (0.52)] and pre- to postoperative improvements for P-UE (p=0.62), ASES (p=0.4), or SST (0.66). ConclusionOur study demonstrates that, at a tertiary level academic institution in a metropolitan city, payor type does not have significant impact on achieving MCID or pre-to-postoperative improvements in PROMs after SA.

P35: A Systematic review on the outcomes of the reverse shoulder arthroplasty versus hemiarthroplasty for the 3- and 4- part proximal humeral fractures in the elderly population

Abstract Background The hemiarthroplasty (HA) and reverse total shoulder arthroplasty (RTSA) are common surgical methods in of the proximal humerus management, where the surgical fixation is not feasible. Our aim is to analyse the most recent data to inform choices on best management for managing 3- and 4 -part fracture dislocations of the proximal humeral fractures in the elderly population. Methods The Medline, PubMed and Scopus databases were searched in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify the relevant literature to include for analysis. The inclusion criteria involved English language, functional outcomes, revision rates, hemiarthroplasty, and reverse total shoulder arthroplasty. The exclusion criteria were publications before 2018, systematic reviews and meta-analysis, other management options such as conservative management, surgical fixation, and total anatomical shoulder replacement. Results The data collected included study design and level of evidence, number of patients and patients’ characteristics, follow-up time post-surgery, functional outcomes, range of movement, Constant score, subjective scores including Disability of Arm and Shoulder (QuickDASH) and American Shoulder and Elbow Score (ASES), and revision rates. Conclusions The evidence suggests that RTSA is the new gold standard management for 3- and 4-part fracture dislocations of the proximal humerus in a selected group of patients over 65 years old with irreparable rotator cuff. The available literature is medium quality, requiring more robust evidence including prospective large cohort studies utilising unified objective and subjective functional outcome scores.

Hydrodilatation and Intra-articular Steroid Injection are Both Effective in Management of Frozen Shoulder: A Case Series

&lt;p&gt;&lt;strong&gt;Background:&lt;/strong&gt; Frozen shoulder is a common problem in general orthopaedic practice, affecting about 2% of the population. Intra-articular corticosteroids (IA) and hydrodilatation have been reported as more effective among other conservative treatments. However, it is unclear which treatment is superior for frozen shoulder, and the hydrodilatation procedure leads to more discomfort in patients since it involves stretching of joint capsule. In this case series, we present 10 cases of frozen shoulder that were treated with hydrodilatation or IA steroid injection. The purpose of this study is to show the effectiveness of hydrodilatation and IA steroid injection in managing patient with frozen shoulder.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods:&lt;/strong&gt; This study was a retrospective case series of patients who received IA steroid injection or hydrodilatation. Five patients underwent IA steroid injection, and another five patients underwent hydrodilatation. The American Shoulder and Elbow Score (ASES) was used to evaluate each patient before and six months after treatment.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Result:&lt;/strong&gt; Hydrodilatation and IA steroid injection showed significant improvement in ASES score assessed at 6-month follow-up.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; Hydrodilatation and IA steroid injection are both effective to treat frozen shoulder in long term follow up.&lt;/p&gt;

Combined, Single-Anchor Subscapularis Tendon Repair and Proximal Biceps Tenodesis Leads to Improved Function and Decreased Pain at 1 Year

PurposeThe purpose of this study was to evaluate the 1-year clinical outcomes of patients treated with combined proximal biceps tenodesis and repair of type II-III subscapularis tendon injuries according to Lafosse et al, using the Loop ‘N’ Tack (LNT) technique. MethodsAll patients undergoing proximal biceps tenodesis and rotator cuff repair (RCR) between March 1st, 2020 and January 30th, 2022 were retrospectively identified. Only patients undergoing combined proximal biceps tenodesis and repair of grade II or III SST injuries with a minimum follow-up of 1 year were included. All patients underwent combined single anchor proximal biceps tenodesis and SST repair using the Loop ‘N’ Tack (LNT) technique. The following outcome scores were recorded at a final follow-up of 1-year postoperatively and were compared to baseline, preoperative values: American Shoulder and Elbow Score (ASES), Single Assessment Numerical Evaluation (SANE), Veterans Rand 12 Item Health Survey (VR-12), and Visual Analog Score (VAS). The minimal clinically important difference (MCID) for all outcome indices was determined with a distribution-based method. ResultsA total of 41 consecutive patients were included. The MCID value for VAS pain, ASES, SANE, and VR-12 mental scores were 0.97, 8.5, 10.9, and 6.0 respectively. At 1-year final follow-up, approximately 95% (39/41) of patients exceeded the MCID for VAS pain scores, 90% (37/41) of patients for ASES scores, 85.4% (34/41) of patients for SANE scores, and 75.6% (31/41) of patients for VR-12 mental health scores. On average, ASES and SANE scores improved by 37 (Pre: 45.2, 1yr: 82.4, p<0.001) and 38 points (Pre: 38.0, 1yr: 75.7, p<0.001) respectively while VAS scores decreased by 4 points (Pre: 5.49, 1yr: 1.48, p<0.001). Approximately 88% (36/41) of patients were satisfied at 1 year post-operatively. Treatment failure was observed in one patient (2.4%). ConclusionPatients treated with combined, single-anchor SST repair and LNT proximal biceps tenodesis achieved significant improvements in function, high satisfaction, and low rates of re-operation at 1 year postoperatively. Additionally, 76% to 95% of patients met the MCID for VAS pain, ASES, SANE, and VR-12 mental health scores. Level of EvidenceLevel IV, retrospective case series

The Functional Outcome of Open Reduction and Internal Fixation of Unstable Floating Shoulder Injuries: A Prospective Study with Good Short-Term and Medium-Term Outcome.

The term "superior shoulder suspension complex (SSSC)" coined by Goss is a bone and soft tissue stable ring made up of clavicular-acromioclavicular strut, the three-process scapular body and the clavicular-coracoclavicular ligamentous-coracoid (C-4) linkage. Disruption at any one site of the SSSC complex makes the other site unstable in a vicious cycle altering the functional anatomy and muscular forces resulting in a "floating shoulder injury" (FSI). The purpose of this study is to evaluate the functional outcome after open reduction and internal fixation of both clavicle and scapula in FSI using Herscovici and American shoulder and Elbow score (ASES) scores. This is a prospective study conducted at level 1 trauma care center in India from May 2019 to May 2023 in 18 cases of unstable FSI. All the cases were followed up post-operatively for a period of 18 months. All the injuries were high energy motor vehicular accidents. Fracture union was seen in all cases with mean period of 13.55 weeks for clavicle and 8.5 weeks for scapula on plain radiographs. 72.22% of the patients had an excellent to good functional outcome assessed by Herscovici scoring system and 61% had an ASES score between 50 and 100. No patient had any adverse complication which precluded their return to their daily activities. Early open reduction and internal fixation of significantly displaced unstable FSIs allows early rehabilitation and better functional outcome.

Inverted-Bearing Reverse Shoulder Arthroplasty: Consequences on Scapular Notching and Clinical Results at Mid-Term Follow-Up.

Background: Scapular notching following reverse shoulder arthroplasty (RSA) is caused by both biological and mechanical mechanisms. Some authors postulated that osteolysis that extends over the inferior screw is caused mainly by biological notching. Inverted-bearing RSA (IB-RSA) is characterized by a polyethylene glenosphere and a metallic humeral liner, decreasing the poly debris formation and potentially reducing high grades of notching. This study aims to report the results of IB-RSA on a consecutive series of patients at mid-term follow-up, focusing on the incidence of Sirveaux grade 3 and 4 scapular notching. Methods: A retrospective study on 78 consecutive patients who underwent primary IB-RSA between 2015–2017 was performed. At a 4 years minimum follow-up, 49 patients were evaluated clinically with Constant score (CS), Subjective shoulder value (SSV), American Shoulder and Elbow score (ASES), pain and range of motion, and with an X-ray assessing baseplate position (high, low), implant loosening, and scapular notching. Results: At a mean follow-up of 5.0 ± 0.9, all the clinical parameters improved (p < 0.05). One patient was revised for an infection and was excluded from the evaluation, two patients had an acromial fracture, and one had an axillary neuropraxia. Scapular notching was present in 13 (27%) patients (six grade 1, seven grade 2) and no cases of grade 3 and 4 were observed. Scapular nothing was significantly associated with high glenoid position (p < 0.001) and with lower CS (70 ± 15 vs. 58 ± 20; p = 0.046), SSV (81 ± 14 vs. 68 ± 20; p = 0.027), ASES (86 ± 14 vs. 70 ± 22; p = 0.031), and anterior elevation (148 ± 23 vs. 115 ± 37; p = 0.006). A 44 mm- compared to 40 mm-glenosphere was associate with better CS (63 ± 17 vs. 78 ± 11; p = 0.006), external (23 ± 17 vs. 36 ± 17; p = 0.036), and internal rotation (4.8 ± 2.7 vs. 7.8 ± 2.2; p = 0.011). Conclusions: IB-RSA is a safe and effective procedure for mid-term follow-up. Inverting biomaterials leads to a distinct kind of notching with mainly mechanical features. Scapular notching is associated with a high baseplate position and has a negative influence on range of motion and clinical outcome.

Kinesiophobia could affect shoulder function after repair of rotator cuff tears

PurposeKinesiophobia (fear of movement) is a major limiting factor in the return to pre-injury sport level after surgery of rotator cuff tears. The study aims to gain insights into how kinesiophobia affects shoulder pain and function after the repair of full-thickness rotator cuff tears.MethodsA prospective study was conducted to evaluate patients who underwent rotator cuff repair between January 2019 and December 2019 in our institution. The patients were divided into a trial group with a high kinesiophobia (Tampa Scale for Kinesiophobia [TSK], TSK > 37) and a control group with a low kinesiophobia (TSK ≤ 37). The indicators of interest included the Constant-Murley scores, numerical rating scale (NRS), visual analogue scale (VAS), Oxford Shoulder Score (OSS), and the American shoulder and elbow score (ASES), shoulder function and strength, and range of motion (ROM) at 3 days, 6 weeks, and 12 months after repair of full-thickness rotator cuff tears.ResultsIn total, 49 patients who underwent repair of full-thickness rotator cuff tears were enrolled, which was divided into a trial group involving 26 patients (mean TSK 52.54) and a control group involving 23 patients (mean TSK 33.43). There were no statistically significant differences in basic information such as age, gender, and length of stay in the two groups. The preoperative and early postoperative functional scores and the Tampa Scale for Kinesiophobia were statistically significant differences between the two groups. However, long-term postoperative follow-up showed no statistically significant difference in ASES, and Constant-Murley scores, OSS, and VAS scores between the two groups as the kinesiophobia changed from positive to negative.ConclusionDegree of kinesiophobia reduced during post-operative rehabilitation of rotator cuff repair patients, but high kinesiophobia is still present in a large portion of the patients after rotator cuff repair. Patients after rotator cuff repair will benefit from early recognition and prevention of kinesiophobia.

Poster 158: Does an In-Situ Biceps Tenodesis with an Anatomic Length-Tension Relationship affect the Incidence of Popeye Deformity and Clinical Outcomes Compared to an Estimated Length-Tension Relationship Technique?

Objectives:Biceps Popeye deformity is a common finding with rupture of the long head of the biceps tendon (LHBT), biceps tenodesis failure or length-tension mismatch during tenodesis. The Popeye muscle is a cosmetic deformity of the arm that may be accompanied by cramping and muscle fatigue and many patients are dissatisfied with the symptoms and appearance. Although prior studies have described physiologic landmarks to optimize the length-tension relationship during biceps tenodesis after LHBT rupture, no study has assessed the biceps muscle appearance after tenodesis “in-situ” prior to the release of the LHBT from the superior labrum for biceps tendon pathologies without complete rupture. Therefore, the purpose of this study is to assess clinical outcomes of an all-arthroscopic technique for biceps tenodesis which maintains the anatomic length-tension relationship of the LHBT prior to tenotomy from the superior labrum. We compared this group of patients to a control group of patients who underwent an interference screw tenodesis technique that required cutting the LHBT from the superior glenoid prior to tenodesis with an estimation of the anatomic length-tendon relationship potentially contributing to subtle biceps Popeye deformity. We hypothesize that an “in-situ” anatomic length-tension relationship tenodesis technique would reduce the risk of a Popeye deformity, reduce cramping and muscle fatigue, and have improved patient-reported outcome measures compared to an estimated length-tension relationship tenodesis with an interference screw.Methods:Consecutive patients who underwent arthroscopic biceps tenodesis with concomitant rotator cuff procedures were enrolled in this study from 2019-2021 and patients were grouped based on a change in senior author’s tenodesis technique, with the initial cohort having an arthroscopic interference screw subpectoral biceps tenodesis after tenotomy from the superior labrum in an “estimated” length-tension relationship technique (Group 1), and the later cohort having an arthroscopic suprapectoral biceps tenodesis “in-situ” with an anatomic length-tension relationship (Group 2) with the LHBT tied to the side of the humerus with all-suture unicortical anchors. Patients were assessed at a minimum of 3-month follow-up and asked about post-operative anterior arm pain and biceps muscle spasms, and if they notice any difference in appearance between their bicep muscles on a 4-point Likert scale (none, mild, moderate, severe). Patient-Reported Outcomes (PROs) of Veterans-Rand 12, American Shoulder and Elbow Score (ASES), EuroQol- 5 Dimension (EQ-5D), PROMIS 10, and Single Assessment Numeric Evaluation (SANE) were collected. Bilateral bicep images of participants were taken in three forearm positions with the elbow flexed 90 degrees: (1) maximal supination, (2) neutral, and (3) maximal pronation. Review of pronation, supination, and neutral forearm rotation bilateral biceps images were evaluated, after blinding and de-identification, by two shoulder and elbow fellowship-trained board-certified orthopedic surgeons for visual appearance and grade of Popeye deformity (none, mild, obvious Popeye). Non-parametric between-group comparison and analysis were performed with statistical significance set at p < 0.05.Results:Sixty-two patients (53% female, age 58.7 ± 9.0 years) were enrolled (33 in Group 1 and 29 in Group 2) with a mean follow-up of 9.8 ± 6.5 months. There were no significant differences between groups with respect to gender, age, and laterality of biceps tenodesis, as well as type and size of rotator cuff repair. There were no significant differences in ASES, EQ5D, and SANE scores between the two technique groups. However, PROMIS 10 Physical Health Scores were significantly improved in Group 2 (15.7 ± 2.3) compared to Group 1 (14.4 ± 2.9) (p=0.03). Patients in Group 2 experienced significantly less pain in their anterior arm than patients in Group 1 (19% vs. 33%, p=0.02) however there were no differences in biceps muscle spasm (3.4% vs. 5.2%, p=0.21). There also were no significant differences in patient-perceived biceps deformity between Group 1 (17.2%) and Group 2 (27%) (p=0.26). Similarly, there were no significant differences in surgeon-perceived biceps deformity between Group 1 and Group 2 (30.3% vs. 24.1%, p=0.47). Interrater reliability for surgeon assessment of a Popeye deformity was found to have a substantial agreement with a Kappa value of 0.77 (p <.0.001), 95% CI (0.645, 0.855).Conclusions:An arthroscopic suprapectoral biceps tenodesis performed “in-situ” with an anatomic length-tension relationship did not reduce the incidence of patient or surgeon perceived Popeye muscle deformity compared to an interference screw tenodesis performed after tenotomy in an “estimated” length-tension relationship technique. Interestingly, the “in-situ” length-tension technique reduced anterior arm pain and improved PROMIS 10 physical health scores post-operatively compared to the “estimated” interference screw technique.

Poster 139: Outcomes After Arthroscopic Assisted Lower Trapezius Transfer: A Retrospective Study

Objectives:Massive irreparable rotator cuff tears lead to significant pain and disability. Tendon transfers have been described as one option to improve pain and function for patients, but clinical data are limited. The purpose of this study was to evaluate outcomes in patients after arthroscopically assisted lower trapezius tendon transfer (AALTT) for massive irreparable rotator cuff tears.Methods:Twenty-one patients with massive irreparable rotator cuff tears who underwent AALTT with a single surgeon from January 2017 to July 2021 were analyzed. Patient demographics such as age, sex, followup, worker’s compensation claims, and prior surgical history were recorded. Preoperative and one-year postoperative range of motion, external rotation strength, and pain visual analogue scale (VAS) were extracted from medical records. Patient reported outcomes measurements used for comparison included American Shoulder and Elbow Score (ASES), as well as Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function and Mental Function. Six-month postoperative MRIs were reviewed when available. Descriptive and univariate statistical analyses were performed.Results:The average patient age was 56.1 (range, 29-72) years and 19 patients (90.5%) were male. The average follow up was 13.2 (range, 4-45) months. Seven patients (33.3%) were involved in worker’s compensation claims and 17 patients (81%) had undergone prior rotator cuff repair. Out of 21 patients who were working at the time of surgery, eleven patients (52.4%) were able to return to their same occupation and 19 patients (86.4%) demonstrated complete tendon healing on postoperative MRI scans (Table 1). There was significant improvement in postoperative pain VAS (5.8±2 vs. 1.7±2) and ASES scores (44.3±18 vs. 71.6±23). No significant changes in PROMIS Physical (47.1±7 vs. 51.4±11) and PROMIS Mental (53.1±8 vs. 53.8±10) were observed. There were significant improvements in external rotation motion (11.0±17 degrees vs. 42.1±13 degrees) and strength (2.9/5 ±1 vs. 4.6/5 ±1) at final followup (Table 2).Conclusions:AALTT is a successful treatment option for the massive irreparable rotator cuff tear. Patients demonstrated significant improvements in pain, range of motion, and strength at one year, with complete tendon healing visualized on postoperative MRI scans.Table 1.AALTT Patient DemographicsTable 2.Ranee of Motion and Patient Reported Outcomes after AALTT

Longitudinal efficacy of acellular dermal allograft following superior capsular reconstruction of irreparable rotator cuff tears

BackgroundSuperior capsular reconstruction (SCR) remains an option for irreparable rotator cuff tears, especially for active patients. While fascia lata grafts were first used with SCRs, acellular dermal allografts have demonstrated similar postoperative outcomes and complication rates. Few studies report long-term clinical outcomes following use of acellular dermal allografts. The aim of the current study is to evaluate long-term efficacy of allograft usage in SCR through patient reported clinical outcomes. MethodsA retrospective review of patients undergoing SCR with use of dermal allografts from 2015 to 2021 was performed. Exclusion criteria included patients lost to follow up, revision or removal of graft, and inadequate follow up timepoints. Demographics and operative characteristics were collected. To evaluate efficacy of graft, numerical rating scale (NRS), American Shoulder and Elbow Score (ASES) were assessed postoperatively. Shoulder range of motion (ROM) was also evaluated by the 6-month postoperative timepoint. Improvement in NRS, ASES, and shoulder ROM from baseline values were evaluated using a t-test. ResultsThe final cohort was 21 patients with two patients undergoing revision and removal of the graft. Mean follow up time was 36.9 months. No major postoperative complications were recorded. Mean preoperative NRS and ASES score was 5.7 and 38.4, which both significantly improved postoperatively (p < 0.001). Patients demonstrated improvements in forward flexion, abduction in 90° rotation, and external and internal rotation. ConclusionUse of acellular dermal grafts in SCR procedures for irreparable rotator cuff tears remains a viable long-term solution to restore shoulder function.

Outcomes of reverse shoulder arthroplasty in patients under 55 years old: Results from the New Zealand joint registry.

The appropriate age at which to perform reverse shoulder arthroplasty is controversial. The aim of this study was to compare the outcomes of reverse shoulder arthroplasty between younger and older patients. Patients who underwent primary reverse shoulder arthroplasty between January 2000 and December 2019 were identified from New Zealand Joint Registry records. Patients were stratified into two cohorts according to age at the time of surgery: < 55 years and ≥ 55 years. These two groups were then compared with regard to baseline characteristics, indications for surgery, revision rates, and patient-reported outcomes using the Oxford Shoulder Score and American Shoulder and Elbow Score (ASES). A total of 5518 primary reverse shoulder arthroplasty cases were identified, with 75 patients < 55 years at the time of surgery (range: 34-54 years). The mean duration of follow-up was 2.36 years (range: 0.11-13.37 years) in the younger cohort and 3.10 years (range: 0.01-16.22 years) in the older patient cohort. Indications for surgery differed significantly between the two groups, with younger patients having higher rates of inflammatory arthritis (p < 0.001), posttraumatic arthritis (p < 0.001), and avascular necrosis (p = 0.049). The younger cohort had an inferior 6-month postoperative Oxford Shoulder Score compared to the older cohort (mean: 28.5 [younger cohort] vs. 35.7 [older cohort]; p < 0.001). There was no significant difference in revision rate between the younger and older patient cohorts during the study period (1.56 [<55 years] vs. 0.74 [≥55 years] revisions per 100 component-years; p = 0.332). Our early results suggest that younger patients undergoing reverse shoulder arthroplasty demonstrate high implant retention rates, comparable to older patients. Longer-term patient-reported outcomes in younger patients are required to guide appropriate patient selection for reverse shoulder arthroplasty. Level III, retrospective case-control study.

The effect of the number of anchors used in the medial row on clinical outcomes in arthroscopic double row repair of rotator cuff tears: retrospective evaluation of patients with 3 to 7 years of follow-up

Aim: Arthroscopic double row (DR) suture anchor repair is one of the most frequently applied methods in the surgical treatment of rotator cuff tear (RCT). Various modifications have been tried to eliminate some of the disadvantages of this technique such as operation time, high cost, and the high risk of retearing. In this study, we aimed to investigate whether placing a single or double suture anchor in the medial row affects clinical and functional outcomes and retear rates in patients with RCT who were operated with the DR suture anchor technique.&#x0D; Material and Method: A retrospective study including 58 patients aged 18-65 years who underwent DR suture anchor repair due to medium-sized RCT and had a minimum follow-up period of 3 years was conducted. One knotless anchor was placed in the lateral row in all patients. In the medial row, we placed 1 all suture anchor (ASA) in group 1 and 2 ASAs in group 2. Visual pain scale (VAS), University of California Los Angeles Score (UCLA), American shoulder and elbow score (ASES) scales were used for preoperative and postoperative clinical and functional evaluation, and complications and retears were recorded.&#x0D; Results: When the preoperative and postoperative VAS, UCLA and ASES scores were compared within groups, there were significant difference from pre- to post-operative findings in both groups (p 0.05). Operation time in Group 1 was significantly shorter than in Group 2 (p

Anatomic and Reverse Stemless Shoulder Arthroplasty: Functional and Radiological Evaluation.

BackgroundStemless shoulder arthroplasty was developed to restore the glenohumeral centre of rotation without violation of the humeral shaft. It allows the preservation of humeral bone stock. Complications related to stem malalignment and periprosthetic fractures can be avoided.Patient and methodsThis is a prospective observational study that reports outcomes of 46 patients who received stemless shoulder arthroplasty “Comprehensive Nano implant ®.” The series includes Group (A): 30 anatomic and one hemiarthroplasty. Group (B): 15 reverse stemless replacement. Functional outcomes were assessed by visual analog score (VAS), satisfaction, range motion, Constant score, and American Shoulder and Elbow Score (ASES).ResultsThe mean follow-up was 40.4 ± 12 months (range, 24 months to 60 months). Group (A): VAS and satisfaction improved by 5.3 and 67.5 points respectively. Constant score significantly improved from 28.5 ± 14.5 to 62.5 ± 23 P = <0.001. The radiological assessment showed the mean centre of rotation (COR) deviation was 2.8 ± 1.9 mm. 27% of patients have COR discrepancy of more than 4 mm. In Group (B), patients reported a significant improvement in VAS, Satisfaction, and ASES P = 0.002, 0.002, and 0.003, respectively.Complications include shoulder pain with progressive loss of movements, aseptic loosening early subscapularis rupture, glenohumeral dislocations, and humeral component migration.ConclusionAnatomic Stemless total shoulder arthroplasty offers acceptable results and improvement of overall functional outcomes.

Travel Distance Does Not Affect Outcomes After Arthroscopic Rotator Cuff Repair

PurposeTo determine the effect of travel distance on achieving the minimal clinically important difference (MCID) on patient-reported outcome measures (PROMs) at least 1 year after arthroscopic rotator cuff repair (RCR).MethodsPatients undergoing primary arthroscopic RCR with a minimum 1-year follow-up at a high-volume tertiary referral center between May 2017 and June 2019 were retrospectively reviewed. Patients were divided into two groups: driving distance of >50 miles from the institution (referral group) and <50 miles (local group). American Shoulder and Elbow Score (ASES), Single Assessment Numeric Evaluation (SANE) score and Constant score at minimum 1-year follow-up were assessed. Chi-square analysis was used to analyze achievement of MCID on any PROM. Subgroup analysis by tear complexity (1 tendon vs. >2 tendons torn) was conducted. Logistic regression was performed to determine whether travel distance and other variables of interest had an effect on achieving MCID.ResultsOf 996 patients reviewed, 385 patients (38.7%) had minimum 1-year follow-up. Of these, 62 (16%) traveled >50 miles to their orthopedic provider, and 212 (55%) had a complex tear. MCID for at least one PROM was reached by 305 (94%) patients in the local group and 56 (90%) patients in the referral group. There was no significant difference between groups in reaching MCID for any PROM. Subgroup analysis by tear complexity revealed no significant difference in preoperative PROMs or achieving MCID postoperatively between referral groups. There was no significant difference between groups when controlling for age, sex, adjusted gross income (AGI), primary health insurance, tear chronicity, and tear complexity.ConclusionsWhen controlling for age, sex, AGI, primary health insurance, tear chronicity, and tear complexity, distance to a high-volume shoulder arthroscopy surgery center did not have an effect on achieving the MCID for any PROM at least 1 year after arthroscopic RCR.Level of EvidenceLevel III, retrospective cohort study.

Biceps Brachii Alterations Following the Latarjet Procedure: A Prospective Multicenter Study.

Purpose: To prospectively investigate the postoperative forearm supination and elbow flexion strength of both upper extremities and popeye deformity in patients who underwent a mini-open Latarjet procedure for anterior shoulder instability. Methods: Patients who underwent a mini-open Latarjet procedure at two specialized shoulder centers were prospectively evaluated preoperatively (T0) and at least 6 months (T1) after surgery. Subjects were tested for elbow flexion and forearm supination strength of both upper extremities using an isometric dynamometer and customized torque dynamometer. Clinical outcome was assessed by the Constant Score (CS), American Shoulder and Elbow Score (ASES) and Simple Shoulder test (SST). Popeye deformity was defined as a distalization of the greatest circumference of the biceps muscle belly towards the lateral epicondyle of the elbow. Results: A total of 20 patients with a mean age of 27 ± 6 years were included in the study. At a mean follow-up of 10 ± 3 months, the elbow flexion strength was restored to the preoperative state (p = 0.240). Forearm supination strength significantly decreased at final follow-up, to 88 % in the surgical arm (p = 0.015) vs. 90 % in the non-surgical arm (p = 0.023). There was no statistical difference when comparing both arms concerning elbow flexion strength (p = 0.510) and forearm supination strength (p = 0.495). No significant popeye deformity was observed in both arms (p = 0.111 vs. p = 0.508). Clinical outcome scores improved significantly from 73 ± 18 to 82 ± 13 (p = 0.014) for CS and 76 ± 22 to 89 ± 12 (p = 0.008) for ASES score preoperatively to final follow-up. No difference in the SST was documented (p = 0.10). Conclusion: The Latarjet procedure showed to preserve elbow flexion strength and provided comparable forearm supination strength compared to the uninjured arm with reliable clinical outcome in this study population. However, a decrease of forearm supination strength in both arms was persistent at a mean of 10 months postoperatively. No popeye deformity was noted in the postoperative examinations.

Good to Excellent Functional Outcome and High Return to Sports Rate after Operative Treatment of Unstable Lateral Clavicle Fractures: Comparison of Two Coracoclavicular Button Fixation Techniques.

Purpose: Operative therapy for unstable lateral clavicle fractures is necessary to reduce the risk of bony non-union. Irritation and restriction during sportive activities due to the implanted materials are a common reason for impaired function and implant removal. The aim of this study was to gain information on functional outcome and time until return to sport (RTS) after surgical treatment of unstable lateral clavicle fractures, comparing two coracoclavicular button techniques. Methods: A retrospective chart review of patients who were consecutively treated for unstable lateral clavicle fractures at our level one trauma center from 2014 to 2018 was conducted. Two different surgical techniques were evaluated and compared. Group 1 was treated using a locking compression plate and knotted DogBone™ Button, while group 2 received an LCP and knotless DogBone™ Button. Functional outcome (ASES (American Shoulder and Elbow Score), Constant-Score, DASH (Disability of Arm, Shoulder and Hand), MSQ (Munich Shoulder Questionnaire) and SPADI (Shoulder Pain and Disability Index) and time until RTS were investigated and compared between both groups, 1 year postoperatively. Results: A total of 56 patients (n = 35 group 1, n = 21 group 2) with a mean age of 45.1 ± 14.6 years met the inclusion criteria. Functional outcome reached good to excellent results (ASES 94.7 ± 9.8, Constant Score 85.1 ± 8.1, DASH 5.5 ± 8.4, MSQ 90.9 ± 7.2, SPADI 96.1 ± 5.7). Implant removal rates were higher in group 1 (48.3% vs. 35.3%) yet without statistical significance (p = 0.122). All patients returned to sports postoperatively with a mean time period until return to sport of 4.6 (3–9) months. Conclusion: Locking compression plating and coracoclavicular fixation using a knotless Dogbone™ technique provides good to excellent functional outcomes, a high and fast rate of return to sport and lower irritation rates compared to the knotted DogBone™ technique.

The American Shoulder and Elbow Score Is Highly Correlated With the Western Ontario Rotator Cuff Index and Has Less Responder and Administrator Burden

PurposeTo compare the correlation, responsiveness, and responder and administrator burdens of the American Shoulder and Elbow Score (ASES) with the Western Ontario Rotator Cuff Index (WORC) for patients undergoing arthroscopic rotator cuff repair to determine whether one score is superior to the other to limit the use of multiple scoring measures when tracking patient outcomes.MethodsA retrospective review of a database of patients undergoing arthroscopic rotator cuff repair was reviewed where the ASES was simultaneously recorded with the WORC. Correlations were determined using the Pearson coefficient. Subgroup analysis was performed to determine if correlations differed in (1) preoperative outcome and (2) postoperative outcome determinations. Responsiveness was determined by calculating the standardized response mean and the effect size of both scores. Responder and administrator burden was examined using 50 consecutively scored WORC and ASES scores by determining the number of questions accurately answered and the length of time taken to score each questionnaire.ResultsCorrelation was excellent for the ASES and WORC (r = 0.90). The correlation of preoperative scores was strong-moderate (r = 0.69), and the correlation of postoperative scores was excellent (r = 0.86). The standardized response mean WORC = 2.3; ASES = 2.2) and the effect size (WORC = 2.9; ASES = 2.8) demonstrated comparable responsiveness. In total, 71.5% of the WORC questions were able to be scored compared with 93.3% for the ASES (P < .0001). The mean time to score the WORC was significantly greater than the ASES (154 vs 23 seconds; P < .0001).ConclusionsThere is excellent correlation and comparable responsiveness between the ASES and WORC. Since there is greater responder and administrative burden for the WORC score, the authors recommend using the ASES over the WORC in patients undergoing rotator cuff repair.Level of EvidenceLevel IV, diagnostic series.

Effect of Age, Gender, And BMI on the Incidence and Satisfaction of A Popeye Deformity Following Biceps Tenotomy or Tenodesis: Outcomes of A Multicenter Randomized Controlled Trial

Objectives:The purpose of this study was to 1) determine the rates of popeye deformity following biceps tenotomy versus tenodesis 2) identify predictors for developing a deformity, and 3) report the subjective and objective outcomes in patients with a popeye deformity.Methods:Data for this study were collected as part of a randomized clinical trial comparing tenodesis versus tenotomy in the treatment of lesions of the long head of biceps tendon. Patients 18 years of age or older undergoing arthroscopic shoulder surgery with intraoperative confirmation of a lesion of the long head of the biceps tendon randomized to one of these techniques were included. The primary outcome measure for this sub-study was the rate of a popeye deformity at 24-months post-operative as determined by an evaluator blinded to group allocation. Secondary outcomes were presence/absence of a popeye deformity based on patients responding to the following question: “Do you notice a bulge on the front of your upper arm above your elbow?” If yes, patients indicated their satisfaction with the appearance of their arm on a 10 cm visual analog scale (VAS) with 0=“Unsatisfactory” and 10=“Satisfactory” as the anchors. Patients were also asked to indicate if they experienced pain or cramping on a VAS, and complete the American Shoulder and Elbow Score (ASES) and the Western Ontario Rotator Cuff score (WORC). Isometric elbow flexion and supination strength (ratio of affected and unaffected) were also measured. Kappa was calculated to measure interrater reliability between patient and evaluator on the presence of a deformity, and logistic regression was used to identify possible predictors of its occurrence. Pearson correlations were performed to identify factors associated with dissatisfaction in appearance.Results:Fifty-seven participants were randomly assigned to each group of which 42 in the tenodesis group and 45 in the tenotomy group completed a 24-month follow-up. The overall incidence of popeye deformity based on clinical assessment was 21%, 9.5% (4/42) in the tenodesis group and 33% (15/45) in the tenotomy group. The odds of a popeye deformity resulting from a tenotomy was 4.3 times that of tenodesis (OR 4.3, 95% CI: 1.25-14.76; p=0.018). Gender was tending towards significance with males having 7.3 greater odds of a perceived deformity (p=0.067), while age and BMI were not predictive. There were no differences between those with and without a perceived deformity with respect to subjective and functional outcome measures. Based on patient self-assessment, the overall incidence of a deformity was 18%, 25% in the tenotomy group and 10% in the tenodesis group. The odds of a patient reporting a popeye deformity following tenotomy was 3.66 relative to tenodesis (OR=3.66, CI 95% 1.08-12.44; p=0.038). Gender, BMI, and age were not predictive of self-report of a popeye. Those with and without a self-reported popeye deformity differed with respect to pain (p=0.001), cramping (0.039), and WORC scores (p<0.006), there was no difference in ASES or elbow strength.Of those who reported having a deformity, mean (SD) satisfaction score reported on the appearance of their arm was 7.3 (2.6). Increasing satisfaction score was significantly correlated with increasing patient age (r=0.640; p=0.025) but there was no association with gender or BMI.Inter-rater agreement between clinical assessment and self-reported popeye deformity was substantial with a kappa of 0.635 (p<0.001). However, 8% (7/87) of patients with a popeye deformity did not perceive it and 3% (3/87) of patients reported a popeye deformity that was not detected by the clinical assessor.Conclusions:The odds of observing a popeye deformity based on clinical assessment following tenotomy was 4.3 times higher than tenodesis at 24-months post-operative. Male gender may contribute to increased incidence, while age and BMI were not major contributors to the presence/absence of a popeye. In patients who reported a popeye deformity, increasing age was associated with increased satisfaction in the appearance of the arm.

Translation, cross-cultural adaptation, reliability, and validity of Turkish version of the university of California Los Angeles (UCLA) shoulder scale into Turkish

Purpose To translate and culturally adapt the University of California Los Angeles (UCLA) shoulder scale into Turkish (T-UCLA) and determine its psychometric properties. Material and methods The UCLA scale was translated into Turkish using Beaton guidelines. Ninety-one patients (46 male; mean age: 46.0 ± 13.7 years) with shoulder disorders completed T-UCLA and American Shoulder and Elbow Score (ASES), Simple Shoulder Test (SST) and 36-Item Short Form (SF-36). Test–retest reliability was tested in 50 patients at a mean of 5.2 ± 2.2 days after initial assessment. Validity was evaluated in 91 patients, and correlations between ASES, SST and SF-36 were analyzed. Responsiveness was assessed in 33 patients who underwent arthroscopic rotator cuff repair with a mean follow-up of 12.8 ± 0.5 months. Results Test–retest reliability of overall T-UCLA, pain and function subscales were 0.96, 0.94 and 0.86, respectively. The correlation coefficients between T-UCLA and SST and ASES were r = 0.752 and r = 0.783, respectively (p < 0.001). The highest correlations between T-UCLA and SF-36 were observed in physical functioning (r = 0.64) and bodily pain subscales (r = 0.66). No ceiling or floor effect observed. Overall and subscales of T-UCLA were highly responsive (ES = 3.22–4.31). Conclusion T-UCLA has sufficient reliability and validity similar to original and translated versions. T-UCLA is responsive in patients who underwent rotator cuff repair. Implications for rehabilitation In this study, Turkish version of the UCLA was found to be a reliable and valid outcome measure in patients with various shoulder pathologies. Turkish version of the UCLA is a very responsive tool in patients with who underwent arthroscopic repair of rotator cuff tears.
